Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What occurs if high resistance joint was left?
The chances are that the resistance will increase, so that in the end there will be no conduction through the joint at all .
What will happen if you connect identical integrated circuits in series?
Connecting integrated circuits is not the same as the much simpler cases of resistors, capacitors, inductors, motors, light bulbs, etc.
Integrated circuits have designated functions, and they operate in concert with the surrounding circuit design. As such, the idea of "connecting identical integrated circuits in series" has no meaning in the general case. You would need to state what kind of integrated circuit is involved.
1,000 ohms and 3,000 ohms in series = total effective resistance is (1,000 + 3,000) = 4,000 ohms.
Power dissipated = I2 R.
I = sqrt( P / R ) = sqrt (.025/4,000) = sqrt(6.25 x 10-6) = 0.0025 A
Voltage drop = I R
Across 1,000 ohms, V = 1,000 I = (1,000 x 0.0025)
= 2.5 volts.
What is the total voltage for R1 20 ohms R2 30 ohms and R3 18 ohms?
As you have not supplied any information, other than the resistance of the individual resistors, there is no way in which your question can be answered.
What properties of semiconductors make them useful in electronic devices?
Any good conductor is has some power loss while it was conducting if we get superconductor at normal temperature state we can send the electricity for a long distance without power loss there we can minimize the usage of semiconductor
Where are periodic signals used?
A periodic signal is a signal that repeats itself over a fixed period of time such as a sinusoidal, square, triangular or sawtooth waveform. So, basically they are used in almost every application of electrical engineering. These periodic waveforms, are also responsible for driving oscillators which is very important in computer applications where a CPU may need to operate according to the clock speed that is determined by the oscillator.
What type of coach bag is no j9 p-9060?
The Coach bag model No. J9 P-9060 is typically identified as a style from the brand's range of handbags. It features a distinctive design, often characterized by Coach's signature materials and craftsmanship. To get specific details about its design, size, or features, it’s best to consult official Coach resources or product listings, as styles can vary widely.

How do you design Power supply for 0-30V and 2A?
Electricity,a power supply has a positive and negative charge,this charge is used by metal,and the metal,or any electric conducter charges from the,negative charge,and the conponent goes out the,positive charge
Why a diode can be used as a frequency multiplier?
A single diode alone can not multiply frequency - it can only divide frequency.
Two diodes in full wave split mode, or 4 diodes in full wave bridge mode, will seem to multiply frequency, due to the fact that alternating polarities of the AC wave will be flipped and superimposed on the resulting DC. It should be noted, however, that this is not true multiplication, because the result is not sinusoidal.
It is possible to filter the output and make it look sinusoidal, but that filter design will be very complex.
*************************************************************
Yes, a diode can be used as a frequency multiplier.
A diode is a non-linear device, and any signal passed through a non-linear device or circuit will result in harmonics being generated. If the signal passing through the diode is not a sine wave then harmonics of all the other frequencies present at the input will also have harmonics generated. There will also be the sums and differences between all the reultant frequencies.
That is why a diode is used as a "detector" in an a.m. receiver. Another name for a detector is a mixer, the other name for which is a multiplier.
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits.
Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
Coulomb is the basic unit of charge in the MKS system. It is the charge which flows per second in a DC current of 1 ampere, about 6*10^18 electrons.
Batteries and capacitors both store charge. They also both store energy. Charge and energy are not equivalent, but are related somewhat like momentum and kinetic energy.
How much voltage is required to run 0.42 A of current through a 15 ohm resistor?
Use Ohm's law:
U= R x I = 3 Ohm x 6 amps = 18 Volts
Thus you need 18 Volts to supply such a load.
Why we use the carrier frequency?
The carrier frequency, as the name implies, "carries" the actual signal to be transmitted. Exactly how this is done depends on the technology being used.
At the other end, the receiver subtracts out (don't take that too literally; again, it depends on the technology used) the carrier frequency, and what's left is the desired signal.
What kind of power is required to supply both resistive and reactive components of a load or loads?
You may be fishing for the answer "AC" or "alternating current", since
no reactive component of power is developed in response to DC.
AnswerSince true power (in watts) is associated with resistive components, and reactive power (in reactive volt amperes) is associated with reactive loads, the vector-sum of these is called apparent power (in volt amperes). So the answer you are looking for is apparent power.
What came first digital or analog service?
Analog services came first, as they were the primary means of communication and broadcasting before the advent of digital technology. Analog systems, such as traditional radio and television, transmitted signals in continuous waves. Digital services emerged later, utilizing discrete signals to improve the quality and efficiency of data transmission, leading to advancements in communication technologies.
What is electrical power measured in?
watts, kilowatts, megawatts, gigawatts...
milliwatts, microwatts, nanowatts, picowatts...
basically all watts.
How noise occur in positive terminal?
noise do not occurs in positive terminals noise like all signals must have a return to be seen as evidence
